Biography
Edward Stafford was born in Brecon Castle, Wales on 3 February 1478, the son of Henry Stafford, 2nd Duke of Buckingham and Catherine Woodville (the sister-in-law of King Edward IV of England). His father was executed in 1483 for rebelling against King Richard III of England during the Wars of the Roses, and it was not until 1485 that Edward - who had remained in hiding after his father's death - became Duke and a Knight of the Order of the Bath. In September 1497, he crushed a rebellion in Cornwall, and he inherited the title of Lord High Constable in 1504, holding that post for the rest of his life. In 1509, he became a member of King Henry VIII of England's privy council. From June to October 1513, he served as captain during Henry VIII's invasion of France. Buckingham would commit treasonous acts when he heard prophecies about the king's death and when he plotted to murder the King, and he was imprisoned and beheaded on 17 May 1521 for his treason.
